Sounds like the new rules want to favor a single team (guess who , RB without a doubt) . They had great aerodynamics in the year 2016 and it was only because Mercedes had a higher power engine it was able to beat them through almost all season. Now with the wider bodies and tires if we add them to a team with great aerodynamics this translates into even better aerodynamics so I think RB is the team to watch out this season with these new rules.
That is what I am thinking also. Also Red Bull Racing has one of the best, if not the best technical director in the sport, Adrian Newey. The wider bodies and tires will make more room for him to work in and figure out a way to add more down force so that they could have the advantage on the turns. I think this will benefit Daniel Ricciardo more than Max.
